Synthesis Wizard
Reagents
The only public collection of DNA parts compling with the ISO-9001 standard.
Browse, retrieve and edit DNA sequences from multiple sources, including iGEM, CIDAR, Agilent Technologies, Sirion Biotech and SEVA.
Don’t compromise and enjoy the only DNA editor that combines the best of both worlds: the ease of use of pre-made biomodules with power of a full-fledged sequence editor.
Harness the power of AI to decouple design from synthesis. Choose among GoldenGate, Gibson, In-Fusion, SureVector, DNAmate and Doulix’s AI will compute the optimal fragments for you.
Less time searching, more time on research with our shopping assistant. Doulix’s AI scans your sequence and pulls together a tailored portofolio of reagents for you from Agilent, SGI-DNA, Sirion and many more.
